I agree and would also suggest, as a workaround for this request but also for anything else we would like to do that is not available in the Identify page, to add a link from the Identify page to the Observation page, here for instance:
When needed, I would right-click on this link to open the Observation page in a new browser tab.
In addition to the “add to project” use case, opening the observation page is also mandatory if I want to Delete an ID, because the ID contextual menu does not allow to delete the ID:
After deleting the ID, I’m in the Observation page in a new tab. If not in full screen mode, I just close it with 1 click on the tab, and I’m back in the Identify page.
But using full screen mode (press F11 from the web browser), I can’t close the Observation page (which I didn’t need). I have first to quit the full screen mode, to access the tabs.
A “Delete” in the contextual menu would be much simpler.
Ctrl-w should close the observation page without quitting full screen.
I agree that having Delete next to Withdraw and Edit in that menu would be convenient, but I seem to recall that they wanted it a little bit buried to encourage withdrawing instead of deleting. I can’t find that discussion though – might have been in the Google Group? Or I might be misremembering.
